System 3 "style" chassis came out the end of J line on a few
TOTL consoles. As far as I know System 3 was never used on
the sets or in literature.
K line brought the name & ad campaign. Sets were 19" & 25".
System 3 was a feature list not a chassis. J & K sets used the
9-153 HV module not the 9-160. They were the most reliable
sets Zenith ever built. Also the CRT's used a green phosphor
that was stunning. One thing I never tried that I would like
to is swap the 9-152 with a 9-152-02 that has a comb filter.
L line brought the 9-160, comb filter, 13" & 17" and RAT tuner.
Reliability dropped but sales went through the roof......
